Added dma_sync_single_range_for_cpu/device to dma-mapping.h in asm-arm &
asm-avr32 to call dma_sync_single_for_cpu/device. This patch enables b44
to compile on systems with these cpus.
This patch was created with the assumption that another method of
dma_sync_single_range_for_cpu/device does not exist on these
architectures.
